英文摘要:
A terahertz laser pulse is used to steer the electron motion after H-2(+) is irradiated by an ultrashort ultraviolet laser pulse. The numerical simulation demonstrates that the ionized electron is pulled out along the polarization direction of the electric field, in contrast, the electrons in the dissociative state move in the opposite direction to that of the electric force. Referring to the coupled dynamic equations for the 1s sigma(g) and 2p sigma(u) states and the analytical solution of the electron localization of the two lowest states of a double-well Coulomb potential model in an external static electric field, one can easily disclose the underlying mechanism for such an electron motion steering.
